0.778ct Fancy Red Heart Cut Lab Grown Diamond Necklace – 9K White Gold with Diamond Halo

0.778ct Fancy Red Heart Cut Lab Grown Diamond Necklace – 9K White Gold with Diamond Halo

Product Description

A symbol of love, reimagined.

This breathtaking necklace features a 0.778ct fancy red heart-shaped lab-grown diamond, framed by a delicate halo of pavé-set white diamonds and suspended from a Cartier-style cross chain in polished 9K white gold. It is romance made tangible – a piece that speaks the language of the heart without saying a word.

The heart cut is the most challenging and romantic of all diamond shapes. Achieving perfect symmetry – two identical lobes meeting at a flawless cleft – requires exceptional skill and precision. When executed perfectly, as this diamond is, the result is a stone that radiates both brilliance and emotion, capturing light from every angle with extraordinary fire.

Red diamonds are the rarest of all fancy-coloured diamonds – far rarer than pink, blue, or yellow. In nature, they are so scarce that most jewellers will never see one in their lifetime. Our lab-grown version delivers the same chemical, physical, and optical properties as its natural counterpart – the same hardness, the same fire, the same intense crimson hue – but at a fraction of the price.

The white diamond halo serves a dual purpose: it amplifies the overall brilliance of the piece while creating a stunning contrast that makes the deep red centre appear even more vivid and saturated. The cool white of the halo and chain against the warm, passionate red creates a visual tension that is nothing short of breathtaking.

Suspended from a Cartier-style cross chain, this necklace lies flat and comfortable against the skin. The chain's sleek, interlocking links provide a refined texture that never tangles or flips – ensuring your pendant stays perfectly centred at all times. An adjustable 5cm extension chain gives you the freedom to wear it at 40cm for a sophisticated choker fit or 45cm for a relaxed, everyday drop.

Why You'll Love It

 The Rarest Colour in Diamonds – Red diamonds are the holy grail of coloured diamonds – rarer than pink, blue, and even the legendary Argyle pink. Owning a red diamond, even in lab-grown form, is a statement of individuality and refined taste.

 The Cut of Love – The heart shape is the most romantic of all diamond cuts. Its perfect symmetry requires master craftsmanship – and when done right, as this one is, it captures light and hearts in equal measure.

 Double the Sparkle – The white diamond halo not only frames the red centre stone beautifully but also adds an extra ring of brilliance. More facets = more light = more sparkle.

 Colour Contrast That Stuns – The cool white of the halo and chain creates a breathtaking contrast against the deep red centre, making the colour appear richer and more vibrant.

 Eye-Clean VS Clarity – Graded VS (Very Slightly Included), this diamond is visually flawless. The tiny inclusions that exist are only detectable under 10x magnification – never to the naked eye.

 The Perfect Chain – Cartier-style cross chain sits flat, doesn't tangle, and keeps your pendant perfectly centred.

 Versatile Length – Adjustable from 40cm to 45cm. One necklace, two stunning looks.

 Ethically Crafted – Chemically, physically, and optically identical to mined diamonds – but sustainable, traceable, and conflict-free.
